GRAIN-SEPARATOR.

SPECIFICATION forming part ofLetters Patent No. 320,358, dated June 16,1885.

Application filed March 25, 1885. (No model.)

To all whom it may concern Be it known that I, EDWARD HUBER, a citizenof the United States, and a resident ot Marion, in the county of Marionand State of Ohio, have invented certain new and useful Improvements inGrain-Separators; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure l is a longitudinal verticalsectional view of a thrashing-machine equipped with my improvements 5and Fi g'. 2 is a plan view of the bottom of the same,which is thesubject of my improvements.

The saine letters refer to the same parts in both the figures.

This invention relates to thrashin g-lnachines or grain-separators andit has particular rei'- erence to certain improvements in theconstruction of the oscillating bottom and the part of the sameoverhanging the shoe, the

Aobjects of the said improvements being to ef- 'ect a more thoroughseparation of the grain from the chaff and straw.

The invention consists in the details of construction and arrangementwhich will be hereinafter fully described,and particularly pointed outin the claims.

In the drawings hereto annexed,A designates the frame of the machine, Bthe strawcarrier, and C the shoe, all of which are constructed in theusual manner, and in which no noveltyT is herein claimed.

D designates the oscillating bottom, which is mounted in suitablehangers and arranged to be oscillated by any suitable mechanism. Saidbottom consists of a solid or imperforate front part, E,the rear end ofwhich overhangs or extends over the front end of the shoe. Said part Eis provided with a series of longitudinal ratchet-bars, F F, increasingin height from the front toward the rear end and extending slightly overthe tail end G of the bottom, which is hinged to the part E, as shown,and which is likewise supported by suitable hangers. Ihe tail end orpart G of the bottom consists of a board, which is provided for thcgreater portion of its length with inverted funnel-shaped perforations HH, its rear end only being left solid or iinperforate. The upper side ofthe bottom board, G, is provided with longitudinal ratchet-bars I I,increasing in height toward the rear end, and terminating in arms J J,which extend over the tailings-spout K. The under side ofthe perforatedportion of the bottoni board, G, is provided with one or more transverseforwardly-inclined dcflcctors L L, the function of which is to interceptthe blast and cause it to act more effectively' upon the materialpassing over the bottom. The board Gis, of course, directly above theriddle M, upon Which the grain falls through the openings H H.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this inven tion will bereadily understood. The ends of the rack-bars F will dump the grain andchai' from the bottom E onto the hinged perforated part G, where it isimmediately exposed tothe blast. The imperforate rear end of the bottomboard, G, prevents straw and chaff from ruiming into the riddle below,thus keeping the latter free from clogging. This imperforate part alsoprevents the blast from acting on the heavy rubbish, and, allowingit todrop upon the ratchet-bars over the said imperferate space, it willagain be agitated and moved outward until the blast will take it againat the rear end of the imperforate space and carry it over the arms orextensions J J of ratchet-bars I I and out of the machine. By thisconstruction the grain is most thoroughly separated from the chaff andall waste avoided.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United Statesl. In a grain-separator, theoscillating bottom having hinged tail section or extension, and providedwith longitudinal ratchet-bars extending slightly over said tailsection, substantially as and for the purpose set forth.

2. The combination, with the imperforate oscillating bottoni, of thehinged tail section, perforated throughout the greater part of itslength, and having imperforate rear end, and the blast-fan,substantially as and for the purpose sct forth.

3. The combination, with the tailings-spout and the oscillating bottom,of the hinged tail section having longitudinal ratehetfbars providedwith rearwardly-extending 4arms extending over the tailings-spout of themachine, substantially as and for the purpose herein set forth.

4. The combination of the oscillating bottoni, the tail section havingimperforate rear end and perforated front end, and hinged to the rearend of the oscillating bottom, and the deleoting-boards securedtransversely under the same, substantially as and for the purposesherein set forth. Y
